For the record, I believe I am not the author of these patches.

I believe the original author is
Signed-off-by: Freddy Xin <freddy@xxxxxxxxxxx>

as recorded in the following code reviews (and testing) that I was
responsible for:
https://chromium-review.googlesource.com/#/q/owner:%22Grant+Grundler%22+status:merged+asix+in_pm

And I would certainly be happy to see this code go upstream and
expected ASIX would submit this change upstream.

FTR, current drivers/net/usb/ax88179_178a.c uses "in_pm" as well.

BTW, I have two additional changes for AX88772x support sitting in my
"needs more work" queue (for quite a while already):
https://chromium-review.googlesource.com/#/c/229620/
"asix: autoneg will set WRITE_MEDIUM reg"

https://chromium-review.googlesource.com/#/c/231162/
"net: asix: see 802.3 spec for phy reset"

I would certainly approve if _anyone_ picked these up, tested them,
and then submitted them to netdev.

cheers,
grant
